I can get you a copy of the launcher itself, in fact you may already have it, the official launcher itself isn't region based, it is the same exe regardless of the region, the urls for the patches are hard coded into the launcher and the region is set from the "System\Settings.cfg" by the line that is "Local ="
example: to use the launcher with your own url you will have to hex edit the launcher itself and change the url, an easy way to find the urls is searching for
Code:
68 00 74 00 74 00 70
The launcher puts null characters in between the letters in the url so http comes out as "68 74 74 70" so you add "00" in between the hex for the letters coming out as "68 00 74 00 74 00 70".
The text in the launcher is also controlled in the "System\Settings.cfg" file, for example the text on top is
Code:
text_caption = "Luna Plus"
The part that gets more complicated is the launcher's look, that is controlled by a tif file and set in the same file like so
Code:
image = data\interface\2dimage\Launcher\c_launcher.tif
